™ Adjust Duty Cycle to Control Fan Speed:
¾ AUTO Temperature– Fan Speed Control (Close-Loop):
AMC Adjusts the DCY to make the Fan Speed Optimum when the Temperature Changes.
No Controller Interference is needed. Run Stand Alone.
¾ RPM-Feedback (as Speed Regulator, Close-Loop): Embedded Controller sets the Target
Speed, AMC Monitors the Speed and Adjusts DCY to Keep the Speed at the Target Value.
Run Stand Alone after setting the Target Speed.
¾ Software – DCY (Open-Loop): Embedded Controller Writes Duty Cycle Register Directly.
